How much does a Proboscis monkey weight?

It is hard to guess what a Proboscis monkey weights. But we have the answer:

An adult Proboscis monkey (Nasalis larvatus) on average weights 12.28 kg (27.08 lbs).

The Proboscis monkey is from the family Cercopithecidae (genus: Nasalis). It is usually born with about 450 grams (0.99 lbs). They can live for up to 21 years. When reaching adult age, they grow up to 64.7 cm (2′ 2″). Usually, Proboscis monkeys have 1 babies per litter.
